The first part of this dissertation deals with the numerical computation of gravity water waves in 3D. The model solves incompressible Euler's equations with a free surface for poterrtial flows. The combination of the Fast Multipole Algorithm with the Boundary Element Method allows to improve significantly the model efficiency. Two applications are then considered : the overturning of a solitary wave over a three dimensional bottom and spatial wave focusing caused by a wavemaker. In the second part, a more qualitative study is carried out in the framework of internat waves in two dimensions. From a system of Korteweg de Vries type, generalized solitary waves are discussed when the velocity approaches the critical value corresponding to the ...
